I doubt it's possible to store Pianocorder data on floppy disk, but
being an audio-type signal, I suggest it can be stored as an audio file
on a standard CD.  Back in the 1970's I developed a method of playing
my Ampico from cassettes.  These days the cassettes are gone, replaced
by the much more reliable CD.  My data format is not the same as the
Pianocorder, but given that both are encoded audio signals, it should
not matter.

To do this you would need to play a Pianocorder cassette into a computer
using the Pianocorder's cassette player (it runs at double speed).  The
resulting audio files can then be burnt to a CD.  Or, you can play the
Pianocorder from a computer, using the audio files you've now stored on
the hard disk.

There's another way.  As Robbie pointed out, visit Mark Fontana's web site,
where you'll see that Mark has developed a system to allow the Pianocorder
to play from MIDI files.  This means you are no longer limited to the
Pianocorder library.
